A study published August 5, 2026 in Neurology Open Access analyzed 12,409 participants over 26 years and found that people aged 45–65 with normal blood pressure, no diabetes, and who do not smoke lived nearly 13 years longer without developing dementia compared to those with all three risk factors. The research, led by NYU Langone's Josef Coresh, suggests midlife vascular health is a critical window for dementia prevention, though the study shows association rather than causation.

  • Three modifiable midlife vascular factors—normal blood pressure, no diabetes, not smoking—are associated with nearly 13 additional years without dementia (ages 45–65).
  • Study of 12,409 people over 26 years found those with zero risk factors lived 30 dementia-free years on average versus 17 years for those with all three.
  • Women and White participants had longer dementia-free lifespans than men and Black participants respectively, highlighting existing health disparities requiring targeted interventions.
  • Study shows association, not causation; measured risk factors only at baseline and did not capture behavioral changes such as smoking cessation over time.

How it unfolded

  1. Report Wider media amplification

    Time Magazine, NBC News, MLive, ScienceAlert, and NYU Langone's own newsroom publish detailed coverage, emphasizing the patient-centered framework and demographic disparities in dementia risk.

    “Our findings argue that people need to actively avert these factors in midlife as a strategy for preserving brain health for more than a decade.”

  2. Report Major news outlets begin coverage

    Coverage from The Washington Post, FOX News, and other major outlets highlight the study's findings that avoiding smoking, managing blood pressure and diabetes during ages 45–65 could extend dementia-free years by up to 13.

  3. Event Study published in Neurology Open Access

    NYU Langone Health researchers published findings from a 26-year analysis of 12,409 participants showing that three midlife vascular risk factors—high blood pressure, diabetes, and smoking—are associated with earlier dementia onset and reduced dementia-free lifespan.

“Discovering new ways to delay dementia is crucial with 42 percent of Americans at risk for developing the condition at any time after age 55.”

Josef Coresh, Epidemiologist, NYU Langone · ScienceAlert ↗ · Aug 8

“Each additional risk factor in midlife was associated with fewer expected years alive and free of dementia.”

Jordan Weiss, Assistant professor, NYU Langone · Time Magazine ↗ · Aug 8

“These results suggest that vascular risk reduction may benefit all groups, but that certain populations, such as Black adults, may especially benefit from targeted prevention efforts.”

Josef Coresh, Study senior investigator · NYU Langone Health ↗ · Aug 8

“The condition dramatically affects people's quality of life. We've also come to appreciate that a lot of dementia is preventable, and a lot of the prevention potential relates to vascular risk factors.”
